Dynamic Bandwidth Allocation using prediction in WDM/TDM passive optical network

In this paper, a new method about bandwidth schedule is proposed by using prediction for the requested bandwidth. The businesses from users are classified. Wavelengths and timeslots are assigned respectively based on the prediction of different classes and the bandwidth requests, the guarantees service level agreements (SLA) of all ONUs. The rule can improve the QoS performances, for example, low delay, high wavelength utilization, and also handle effectively for date stream bursting.
